During operation, a transmitter in an electronic device may provide, to a transmission path, an electrical signal. This electrical signal may be divided by the power splitter into a first output electrical signal in a first output transmission path and a second output electrical signal in a second output transmission path, which may result in transmitting of the first wireless signal and the second wireless signal by antennas. Because the second output transmission path may include a delay element that provides a delay, the second wireless signal may be delayed relative to the first wireless signal. Moreover, N radar receivers in the electronic device may receive first wireless-return signals corresponding to the first wireless signal and second wireless-return signals corresponding to the second wireless signal. These wireless-return signals may be combined to create a virtual array MIMO radar having an antenna aperture size of 2N.
Legal claims defining the scope of protection, as filed with the USPTO.
2. The electronic device of claim 1, wherein the electrical signal comprises a pulse.
3. The electronic device of claim 1, wherein the second wireless signal is delayed by the delay period relative to the first wireless signal.
4. The electronic device of claim 1, wherein the first wireless signal comprises a first pulse and the second wireless signal comprises a second pulse.
5. The electronic device of claim 1, wherein the electronic device is configured to provide, from the radar transmitter, one or more additional instances of the electrical signal to the transmission path in the transmission circuit.
6. The electronic device of claim 5, wherein the one or more additional instances of the electrical signal are provided based at least in part on a time interval corresponding to a pulse repetition frequency (PRF).
7. The electronic device of claim 6, wherein the delay period corresponds to substantially one half of the PRF.
10. The non-transitory computer-readable storage medium of claim 9, wherein the electrical signal comprises a pulse.
11. The non-transitory computer-readable storage medium of claim 9, wherein the first wireless signal comprises a first pulse and the second wireless signal comprises a second pulse.
12. The non-transitory computer-readable storage medium of claim 9, wherein the operations comprise providing, from the radar transmitter, one or more additional instances of the electrical signal to the transmission path.
13. The non-transitory computer-readable storage medium of claim 12, wherein the one or more additional instances of the electrical signal are provided based at least in part on a time interval corresponding to a pulse repetition frequency (PRF).
14. The non-transitory computer-readable storage medium of claim 13, wherein the delay period corresponds to substantially one half of the PRF.
17. The method of claim 16, the first wireless signal comprises a first pulse and the second wireless signal comprises a second pulse.
18. The method of claim 16, wherein the method comprises providing, from the radar transmitter, one or more additional instances of the electrical signal to the transmission path, the one or more additional instances of the electrical signal being provided based at least in part on a time interval corresponding to a pulse repetition frequency (PRF).
19. The method of claim 18, wherein the delay period corresponds to substantially one half of the PRF.
